A rendering of the inner Solar System showing the asteroids discovered by Rubin in light teal. Known asteroids are dark blue. The rendering shows a total of almost 12,700 asteroids that were discovered with Rubin over the span of 1.6 years: 73 were discovered during the first early test observations using Rubin’s Commissioning Camera in late 2024 and released as part of Rubin’s Data Preview 1 in Summer 2025; 1514 were discovered during First Look observations in April and May 2025; and the recent 11,000+ asteroids were discovered using observations taken during Rubin’s early optimization surveys in Summer 2025. These are the locations of objects at the time of each object’s discovery. In the time since discovery, the objects have continued in their orbits around the Sun and dispersed from the narrow “pencil beam” rays seen in this graphic.

This artist’s illustration represents the start of the alert stream from NSF–DOE Vera C. Rubin Observatory. The summit facility is shown on a rocky ridge. The night sky features stars and the glittering band of the Milky Way Galaxy. The sky is populated with multiple alert “pings,” representing individual alerts from Rubin that something in the sky has changed in brightness or position. Different icons represent various types of alerts, including asteroids, supernovae, active galactic nuclei, and variable stars.

This artist’s illustration depicts 2025 MN45 — the fastest-rotating asteroid with a diameter over 500 meters that scientists have ever found. The asteroid is shown surrounded by many other asteroids, depicting its location within the main asteroid belt. The Sun and Jupiter are shown in the distance. 2025 MN45 is 710 meters (0.44 miles) in diameter, and it completes a full rotation every 1.88 minutes. The discovery was made using data from NSF–DOE Vera C. Rubin Observatory, jointly funded by the U.S. National Science Foundation and the U.S. Department of Energy's Office of Science.

A good comparison of the ComCam engineering test camera with the LSSTCam can be seen in the figure. The two have the same resolution and sensitivity, but the LSSTCam covers 21 times more area on the sky in every image. A single test engineering image from the very first night of the ComCam campaign, before any detailed tuning or more precise alignment of the optical system, is shown in the context of the coverage that will be provided by the LSSTCam: every one of the 21 squares in the teal wire frame is equivalent to another ComCam, all observing the sky at the same time. As ComCam already covers an impressive area equivalent to two full Moons, the promise of the full LSSTCam is incredible.
